1 User instructions
Valve terminal type VTSA-ASI-...-8E8A-Z has been de
signed exclusively for controlling pneumatic actuators and
is only suitable for use in bus systems in accordance with
the AS-Interface specifications. If additional commercially-
available components are connected, the specified limits
for pressures, temperatures, electrical data, torques, etc.
must not be exceeded.
The valve terminal enables the control of 8 valve solenoid
coils and the registering of 8 sensors. The exchangeable
connections of the CPX system are used for connecting the
sensors.
AS-Interface bus systems and valve terminals may only be
installed by personnel especially trained for this purpose.
Specifications on the design and addressing of your bus
system can be found in the manual for the AS-Interface
master.
Detailed information on the pneumatic components of the
valve terminal can be found in the Pneumatics manual type
P.BE-VTSA-...
Caution
SSwitch off the power supply before connecting or
disconnecting plugs (otherwise this could lead to
functional damage).
SCommission only a valve terminal which has been
fitted and wired completely.
SConnect the earthing cable between the adapter
module and the multipin node.

3 Installation instructions
3.1 Mounting the valve terminal
The valve terminal can be fastened in hat rails or mounted
on a wall.
Note
In order to guarantee resistance to shocks and vibra
tion, the maximum distance between the fastening
points must not exceed 280 mm.
3.2 Connections and address assignment of the inputs
The valve terminal uses the exchangeable connections of
the CPX system. Replace the sub-base as follows:
1. Loosen the 4 screws in the sub-base 9with a TORX
screwdriver size T10.
2. Pull the sub-base 9carefully and without tilting away
from the electrical plug connector.
3. Insert the new sub-base. Tighten the 4 screws of the sub-
base (tightening torque of the screws 0.65Nm±10%).
4. Make the necessary connections. Seal unused connec
tions with protective caps.
Note
The sub-base CPX-AB-4-M12x2-5POL (-R) must not be
used.

3.3 Address assignment
Before connecting to the AS-Interface bus: assign an
unused address to each slave.
Note
Valve terminal type VTSA-ASI-...-8E8A-Z contains two
AS-Interface slaves. The valve terminal behaves on the
AS-Interface bus like 2individual valve terminals each
with 4 inputs and 4 outputs.
– Permitted address range for each slave: 1 … 31
(Factory settings: 1 for slave 1, 2 for slave 2).
– It is not necessary to parametrize the AS-interface
slaves.
Address both slaves one after the other at the plug
“AS-iIn” (see section 3.5).
Note
Never assign the same address to both slaves.
The assignment of the data bits to the inputs and outputs
of both independent slaves is shown in the following
diagram.
Slave 1: IO code 7HSlave 2: IO code 7H
Data bits: D0 D1 D2 D3 D0 D1 D2 D3
I/O I/O I/O I/O I/O I/O I/O I/O
Inputs: I0 I1 I2 I3 I4 I5 I6 I7
Outputs:
(solenoid coils)
O0 O1 O2 O3 O4 O5 O6 O7
I/O = Bidirectional (B)
The address mapping depends on the configuration of the
master.

Festo VTSA-ASI-...-8E8A-Z 2018-11b English10
3.4 Address assignment of the solenoid coils
Depending on the linking up to 8 valve locations can be
assigned. The following applies to VABV...T2:
– solenoid coil 14 occupies the lower-value address,
– solenoid coil 12 occupies the higher-value address.
Addresses are assigned on the solenoid coils in ascending
order without gaps, from left to right.
The number of assigned addresses per valve location
depends on the manifold base, irrespective of whether
valves or cover plates are fitted.

3.5 Connect the AS-Interface bus and the load voltage
The sensor supply for the inputs is provided via the
AS-Interface bus.
Warning
SUse only PELV (protective extra-low voltage) circuits
as per EN 60204-1 for the electric power supply.
SAlso observe the general requirements for PELV
power circuits as per EN 60204-1.
SOnly use power sources which guarantee reliable
electrical isolation of the operating voltage as per
EN60204-1.
Through the use of PELV circuits, protection against
electric shock (protection against direct and indirect
contact) is guaranteed in accordance with EN 60204-1.
Note
The sensor supply gained from the AS-interface power
supply is protected against short circuits and overload.
It must not be connected with other potentials
(example, a common ground).
The valves (outputs) are always supplied with 24 V
additional supply, separate via the load voltage
connection.

Please note with branch lines:
– the maximum total length of the AS-Interface bus
(100 m without repeaters/extenders)
– the length of the load voltage connection cable
(depends on the current consumption of the valve
terminal and fluctuations in load voltage).

1) The inputs are short-circuit resistant. In the event of a short circuit
the slave will be switched off. The AS-Interface master then regards
this slave as missing. The slave reports back as functioning once the
short circuit has been eliminated.
